Ramp creates power as cars pass

"A road ramp that uses passing cars to generate power has been developed.

Dorset inventor Peter Hughes' Electro-Kinetic Road Ramp creates around 10kW of power each time a car drives over its metal plates.

More than 200 local authorities had expressed an interest in ordering the £25,000 ramps to power their traffic lights and road signs, Mr Hughes said.

Around 300 jobs are due to be created in Somerset for a production run of 2,000 ramps next year.

Plates in the ramp move up and down as vehicles pass over them, driving a generator.

'The ramp is silent, comfortable and safe for vehicles,' Mr Hughes said.

Depending on the weight of the vehicle passing overhead, between five and 50kW can be generated."
